1. A dielectric waveguide comprising:
a dielectric substance wiring configured to propagate a terahertz wave;
a medium disposed around the dielectric substance wiring, the medium having a large refractive index difference with respect to the dielectric substance wiring;
a holding unit configured to hold the dielectric substance wiring; and
a low-refractive index cladding layer disposed between the holding unit and the dielectric substance wiring, wherein
the terahertz wave is confined within the dielectric substance wiring.
